چکیده

A parameter-free and global-oriented method of optimal field synthesis is proposed. The key idea is to consider the boundary of the field region to synthesize as a moving boundary, whose velocity leading to the optimal solution is unknown. The proposed method does not require to solve the transport equation and the adjoint variable problem. The design optimisation of the guard ring in a high-voltage transformer is considered as the case study. Finite-element method and conformal mapping method are used for field analysis. Streszczenie. W artykule zaproponowano otymalną syntezę pola przy użyciu metody globalnie zorientowanej ze szswobodnymi parametrami. Kluczową ideą jest rozważenie brzegu obszaru polowego, który ma podlegać syntezie, jako brzegu poruszającego się w kierunku optymalnego rozwiązania z nieznaną prędkością z prędkością. Proponowana metoda nie wymaga rozwiązywania równania transport ani problem sprzężonego. Optymalny projekt pierścienia ochronnego w transformatorze wysokonapięciowym stanowi przykładowe studium przypadku. Do analizy pola wykorzystano metodę elementów skończonych i metodę odwzorowań konforemnych.(Podejście kinematyczne do syntezy optymalnego kształtu pola elektrycznego).

Dexterous Workspace Shape and Size Optimization of Tricept Parallel Manipulator

This work intends to deal with the optimal kinematic synthesis problem of Tricept parallel manipulator. Observing that cuboid workspaces are desirable for most machines, we use the concept of effective inscribed cuboid workspace, which reflects requirements on the workspace shape, volume and quality, simultaneously. The effectiveness of a workspace is characterized by the dexterity of the manip...

Effect of Cell Size and Shape on Electric Field Threshold and Critical Transmembrane Voltage for Electroporation

Introduction:  Electroporation  is  a  technique  for  increasing  the  permeability  of  the  cell  membrane  to  otherwise  non-permeate  molecules  due  to  an  external  electric  field.  This  permeability  enhancement  is  detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the  pulse  strength  threshold.  In  this  study,  the  variabil...

Kinematic Synthesis of Parallel Manipulator via Neural Network Approach

In this research, Artificial Neural Networks (ANNs) have been used as a powerful tool to solve the inverse kinematic equations of a parallel robot. For this purpose, we have developed the kinematic equations of a Tricept parallel kinematic mechanism with two rotational and one translational degrees of freedom (DoF). Using the analytical method, the inverse kinematic equations are solved for spe...
